3-D FE Method Analysis of Static Fields for Non-Conforming Meshes With Second-Order Node-Based Elements

A novel approach of using node-based, second-order polynomial shape functions to substitute the degrees of freedom corresponding to slave nodes by a linear combination of those corresponding to master nodes is shown to be a powerful and accurate tool to couple non-conforming meshes. This method is investigated and proposed to be used to consider moving domains, especially rotating parts. The numerical behavior is illustrated by an exhaustive accuracy investigation.
